The larynx is a structure extending from the epiglottis to the superior portion of the trachea that protects the lower respiratory tract from food aspiration. The structure is composed of several cartilages, joints, muscles, and fibroelastic tissues.
Cartilages include:
- Epiglottis
- Thyroid
- Arytenoid
- Cuneiform
- Corniculate
- Cricoid
Joints include:
- Cricothyroid
- Cricoarytenoid
Muscles can be divided into three different groups with innervation (see keyword linked below):
- Tensor Muscles
- Cricothyroid
- Adductor muscles
- Lateral Cricoarytenoid
- Interarytenoid
- Thyroarytenoid
- Abductor muscles
- Posterior cricoarytenoid
